Jetting?

[Martin Blair]

What jetting should i be running I have a UNI filter with no lid, and a bill ballance slipon pipe, that it right now im running a 180 main and stock for the rest, it just feels like its not revving fast enough any suggestions?

80 is way small... ha. try to lean it out some for more throttle response. maybe mess with the air screw or go down a jet size. 175-178. whatever the next size is

I THINK THE 180 JET IS JUST A BIT LARGE FOR WHAT YOU HAVE, TRY GOING TO A 175 OR 170 JET AND ADJUST YOUR AIR FUEL MIXTURE SCREW. ALSO IF YOU HAD A PIPE THE 180 WOULD WORK JUST FINE. READ YOUR SPARK PLUG, IF ITS BLACK YOUR PROB TOO RICH - YOU WANT A NICE CARDBOARD BROWN COLOR FOR GOOD PERFOMACE.
:D
